An ability to turn "on" and "off the pyro-, piezo-, or ferroelectric properties of materials on demand by optical means leads to fascinating device applications and is central to modern
photostriction, where material strain is generated by light.
The underlying mechanism of
photostriction remains unclear, adds Uchino, though he believes it arises from "some combination of photovoltaic and piezoelectric effects."
